Donald Trump will become the 45th US president after a stunning victory over Democrat Hillary Clinton.
The Republican nominee's victory came down to a handful of key swing states, despite months of polling that favoured Mrs Clinton.
The battlegrounds of Florida, Ohio and North Carolina cleared the way for his Brexit-style upset.
Global markets plummeted, with the US dollar diving and gold prices surging.

Mr Trump's shock victory in Wisconsin put him over the 270 out of 538 electoral college votes needed to win the White House, after a gruelling and rancorous campaign.
The US president-elect took to the stage with his family at his victory rally in a New York hotel ballroom and said: "I just received a call from Secretary Clinton. She congratulated us on our victory.

"Hillary has worked very long and very hard over a long period of time, and we owe her a major debt of gratitude for her service to our country."
He added: "It is time for us to come together as one united people."
The real estate tycoon, former reality TV star and political newcomer, who was universally ridiculed when he declared his candidacy in June last year, said his victory had been "tough".
Mr Trump has so far won 28 US states, smashing into Mrs Clinton's vaunted electoral firewall in Pennsylvania and Wisconsin, states that have not supported a Republican presidential candidate since 1988 and 1984 respectively.
He also prevailed in Iowa, which has not elected a Republican since 2004.
Mr Trump held on to solidly Republican territory, including in Georgia, Arizona and Utah, where the Clinton campaign had invested resources in the hope of flipping the states.
